Missfire help

i got a CEL that said cyl #1 missfire car seemed to run fine. just installed a walbro 255 pump SAT but had no issues until today. car has 87,000mi and hasn't had the plugs changed since 60,000 could that have something to do with it?

Yes.. I had missfire codes with my upgrades until I swapped to colder NKG plugs..

1 colder? i thought that was only good if you were running 17+ psi all the time im only stage2 only hits 15psi sometimes never any more than that
it was just weird that i had a cel the only one i'd ever had was fuelcut before this

I'm sorry, I was not suggesting that you switch to colder plugs, I was saying that it helped in my situation. I am however suggesting that you replace your plugs and verify proper gapping..

right on i'd like to check them out too since i was lazy and had the dealer do it but the cel hasn't come back on since i reset the ecm thanks for the advice !
